All societies have their standards/socialnorms of behaviour and attitudes. Deviating from them can be seen as abnormal
Limitation: Social norms are subjective and vary across cultures and subcultures. What is normal and excepted in one culture may seem strange to another
One limitation is that it can be used to justify the removal of "unwanted" people from a society
Limitation: Social norms change over time e.g what was considered normal in the past (going to school on a donkey) may not seem normal today
